I decided to replace my wheel bearings, and in the process replace my brake pads. Both of which I have never done before. I had my rusty mechanic dad helping, and everything went fine on the bearing replacement. The problem is the darn brake pads. I went to Autozone and bought the Duralast Ceramic pads. Once we installed them, we can't get the new pads over the rotor. We pushed the caliper back, but it seems like the rotor is about 1/2 inch wider than the caliper with the pads. What am I missing? Do they make a thinner pad? It has to be something stupidly simple.
